小程序封装网络请求

utils/util.js

const wxRequest = (url, params, successCallback, errorCallback,
completeCallback) => {   
wx.request({
url: getApp().globalData.domain + 'index.php/api/' + url,
data: params || {},
header: { 'content-type': 'application/json' },
method: 'POST',
success: function (res) {
  if(res.statusCode== 200){
    successCallback(res.data)
  }else{
    errorCallback(res)
  }
},
fail: function(res) {
  errorCallback(res)
},
complete: function (res) {
  completeCallback(res)
 }  
}) 
}
module.exports = {   
 formatTime: formatTime, 
 wxRequest:wxRequest   
}

app.js设置请求域名

globalData: {
domain:'http://122.51.181.214/',
userInfo:null   
}

发起请求
引入const util = require(’…/…/utils/util.js’)

loadIndex:function(){
var url = 'Index/index'
var params = {}
util.wxRequest(url, params, data => {
  console.log(data)
  this.setData({
    banner:data.banner,
    ad:data.ad
  })
},data => {},data => {})   },
